IMPROVEMENT IN BEE-R-FAUCETS.

Specification forming part of Letters Patent No. 221,829, dated November 18, 1879 application filed June 16, 1879.

To all whom it may concern:

Be it known that I, CHARLES KARsrnNs, of the city and county of San Francisco, and State ot' California, have invented an Improved Beer-Faucet; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings.

My invention 'has reference to an improved tap and faucet for beer and other barrels and casks in which a liquid wis contained under pressure.

Referring to the accompanying drawings, Figure lis a longitudinal section. Fig. 2 is a front view of the plug A.` Fig. 3 is a detail view of the tap with the loose coupling-ring U. Fig. 4 is a section of the small plug I.

Let A represent a tapering metal tap or plug, which is provided with screw-threads around its exterior, so that it can be turned into a hole in the head of the barrel or cask. The plug or tap will then form a permanent part of the barrel or Cask. The interior of this tap is bored. out, so as to form an inner and outer chamber and an intermediate passage connecting them. The inner end of the plug is left solid, except a small hole, c, in its center 5 but just inside of this solid end a chamber, f,is made, as shown. The outer end, lc, of the plug is bored out for a short distance, and this bored-out portion is tapped with screw-threads. A smaller hole, g, is then made centrallyT through the intermediate portion of the plug, so as to connect the outer and inner chambers, and this hole is also tapped with screw-threads. The shoulder around the hole g at the base of the outer bored portion will then form a seat, l, on which a leather or other packing-ring can be placed.

I is a small plug, onehalf of which is just as large in diameter as the hole g, and this end is cut with screw-threads, so that it will The pin is then headed on its outer end outside of the disk, so that the'disk will rotate freely upon it. The outside face of the disk is bored out, and a suitable packing is inserted in the bore, so that when the plug is turned down the packing in the end of the disk will press upon the raised rim xaround the edge ofthe hole e and effectually close it. A hole, r, is made transversely through the threaded portion of the plug just above the disk j, and another hole, s, connects with this transverse hole and passes centrally through the outer square end of the plug, as shown.

The faucet T which I use is the ordinary beer-faucet, such as brewers ordinarily use for drawing beer from barrels or casks, only I provide its inner'end With a loose coupling-ring,

a, which is cut With screw-threads, so that it will turn into the threads in the outer end of the plug` A. This ring is kept in place by a flange or rim, e, as shown. Y

After the tap A has been secured in the barrel or cask I turn the screw-plug I into the connecting-hole g until its packed end i's pressed tightly over the hole e in the inner end of the tap, the disk j rotating sufficiently to allow the packing to seat itself without torsion. This prevents the beer from entering the tap A. v l

When it is desired to tap the barrel or cask the small end of the faucet is .placed in the outer bore of the tap, and the square outer end of the screw-plug inserted into the corre sponding hole in the faucet. I then turn the coupling-ring u with a spanner into the outer end of the tap until the face of the ilange c is seated firmly on the packed shoulder or seat around the hole g. Having insured a tight joint at this point I turn the faucet, so as to unscrew the screw-plug I, and raise its lower end from the hole c, so that the beer can pass into'the chamber f. Thenceit passes through the holes 1' and s into the faucet and is ready to be drawn.

It will be noticed that I turn the end of the faucet firmly upon the seat in the tap before turning the beer into the faucet, so that there is no chance for it to leak.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

l. The tap A, provided with the inner chamber, f, intermediate threaded passage, g, and outside chamber, K, threaded as described, and having the hole e, with its raised rim x, in its inner end, in combination with the screwplug I, with its rotary disk end j and its packing, said screw-plug having` the holes r s, all combined and arranged substantially as and for the purpose described.

2. The tap A, provided with a seat or shoulder, Z, near its upper end, and having the perforated screw-plug I, with its square outer end,

and the rotary disk j at its lower end, arranged to close a hole, e, in its inner end, in combination with the faucet T, with its loose ringcoupling u and flange or rim w, all combined and arranged to operatev substantially as and for the purpose described.

In Witness whereof I have hereunto set my hand and seal.
